' OF DELAWARE Application filed April 7,

To aZl 'whom it may concern:

Be it known that we, LOWELL F. LTNDLEY and ALEXANDER S. Srnnn, citizens of the United States, and residents of Chicago,

county of Cook, and State of Illinois, have jointly invented certain new and useful Improvements in Surfacing-Machines for Roofing, of which the following is aspecificat'ion, and which are illustrated in the accompanymg drawings, forming a part thereof.

The invention relates to a machine for producing roofing and has for an object the provision of amachine that will produce roofing having definite areas'thereon, sur- 5 faced with materials of distinctive appearance. A'further object is the provision of roofing which is novel in the manner which it is cut from the continuous sheet and placed together on a roof.

In the drawings- 1 Figure 1 is a side elevation, diagrammatically shown, of a machine embodying the invention.

Figs..2, 3, and 1. are edge views of various modifications of disks that may be used, the

sheet of roofing being shown. in section.

Figs. 5 and 6 are plan views of different forms of continuous sheets provided by the invention;

form of roofin assembled.

Fig S is a etail section on line 88 of Fi 5, and

' i 9 is a plan view of a form of shingle provided by the invention.

The roofing provided by the invention is formed in continuous sheets and afterward cut into strips either lengthwise or crosswise of the ori inal sheet, according to the effect desired, w ich strips are then assembled on the roof in overlapping relation.

The machine diagrammatically shown in the drawings for producing the roofing, in each of its forms comprises spaced disks mounted on a common shaft, the form and spacing of the disks varying according to the eifect desired.

In the form of Figs. 1 and 2 the disks 10, have their edges corrugated and are mounted on a shaft 12. As shown the corrugations are. angular but curved corrugations might .Speeifieation of Letters Patent.

equally well be used to secure cor change in effect. respondmg For the purpose of producing the design in Fi 5 ad'acent dlsks, 1n the form shown in ig. '2, a re arranged with their corrugations out of phase, that is to say, oppositely directed crests of corrugatlons of adjacent disks are circumferentially arranged to be in juxtaposition. The material utilized as a base in the productlon of the roofing is preferabl the well Xny desirable or suitablefabric may, however, be used as a base in the carrying out of the invention. The sheet of base material 13 bearing a coat of bltuminous material '14 in a sticky condition is led about a guide roller 16, in contact with disks 10, about a second guide roller 11, and between a pair of pressing rollers 17, 18.

The sticky coating may be applied to the sheet,13 by any usual and well known rocess. The sheet, thus prepared is paced under tension suflicient to cause the edges of the disks to press into the sticky coating and to penetrate substantially to the bottom thereof. The edges of the" disks are, as

shown, given a blunt form, that they shall not in any manner damage the roofing base.

To supply the surfacing material to the machine, hoppers 19, 20, v21, 22 are shown,

each provided with a spout 23, 24, 25, 26,

to delivermaterial to a space between the respective disks 10. The material supplied by adjacent spout is preferably of different appearance. That supplied to the space be tween alternate disks will be alike when a two color effect is desired. The surfacing material used is preferably a granular material produced by a crushing process and is desirably such as has a distinctive 'color given by nature. A very suitable material is slate which occurs ina variety of pleasing colors and is readily crushed and produces particles of advantageously flattened shape. Other desirable materials are copper-slag, shells, gravel and sand.

The sheet base material is shown as being in contact with the disks 10, thr'ou h considerably more than one half their diameter. The granular material is fed to the spaces between the disksat such a speed that there w1ll always be a surplus present, which will be carried upward by revolution of thedisks until it falls away from the sheet by gravity,

only those particles actually adhering to the to form alternate radial ribs and grooves',.

and'that the adjacent disks are symmetrically arranged so that thelribs and grooves of each disk will register with the rlbs and grooves of-adjacent disks. The disks are so spaced that there is an appreciable distance between the crests of adjacent ribs of adjacent disks and the roofing sheet forms with these disks a series of pockets in which the granular material such as crushed slate tumbles on the sticky surface of the sheet and coats completely all of the sticky surface 1 with which it comes in contact. Any excess remains in the pocket for future use and is periodically replenished from the hopper above and does not at any time become contaminated with granular material of another color from an adjacent pocket.

After the sheet 13 with its coating 14 and adhering granular material has passed over roller 11'it is led between press rollers.17, 18, which press the granular material firmly ifnto the coating 14 and leave a regular surace. j i The surplusg'ranular materia'l supplied to the portion of the base 13 projecting at each side beyond the outer disks 10 will spill off from the edge of the sheet and will be collected and reapplied. I

The form of disks illustrated in Figs. 1 and 2 will produce a sheet of material such as illustrated in Fig. 5, wherein areas 27 and 28 are preferably of contrasting colors and will be separated by accurately drawn, sh arp edged, depressed lines as indicated in Fig. 8, which lines will be free of granular mate- 'rial'. For use on a roof it is preferred to cut the sheet of Fig. 5 on the dotted lines of that figure and to apply the resulting strip sheets lengthwise u on the roof in overlapping relation as indlcated in Fig. 7.

The form and arrangement of disks shown in Fig. 3 will produce the sheet of material shown in Fig. 6, in which the areas 29, and 30 are preferably of contrasting colors separated by depressed lines as abovedescribed. This form of roofing is preferably cut into strips transversely of the sheets as indicated by the dotted lines on Fig. 6, which strips may be laid in courses lengthwise of the roof, the strips in each course abutting and the successive courses overlapping. It is preferred to lay the strip of successive courses with the narrow areas instaggered relation to give an effect of broken joints. The outside edge areas 29 of Fig.6 are indicated as being one half as wide as the remaining areas of like color. When the strips are abutted these end areas will therefore combine to produce an area of normal width.

The form of machine of Fig. 4 isdesigned to produce a sheet of material of alternating wide strips of contrasting colors separated by sharp, depressed, unsurfaced lines, as in the other forms described. The thus produced sheet is preferably out as indicated by the dotted lines on Fig; 4 to produce separate shingles the halves of which are of contrasting colors. Such shingles may be laid with either end exposed to produce an entire roof of either of the two colors which each shingle carries. V

The depressed lines have. a structural utility in addition to their function of separating the areas of contrasting appearance. Roofing of the nature under consideration is found to have a tendency to buckle or pull into waves, to some extent, no matter how carefully manufactured and laid. In the roof of the present invention such buckling is in part localized by the depressed lines since these lines have less rigidity than the remaining portion of the material.

The disks 10 especially when of the form of Fig. 1 should have the same peripheral speed as the speed of travel of the sheet of material 13 in order that theremay be no relative. motion between'the sheet and the disks. This may be accomplished by propolling the sheet of material and allowing thereby.

- While the roofing material is being passed the disks to turn freely and be driven aboutthe disks it will have impressed on it a.

plurality of wavy lines spaced apart from each other a distance's'uch that the web of material may be split between the lines without the line of. cut touching any of the impressed lines. That is to say, the straight lines of cut will be in areas of material which has no impressed marks or lines on it. When the sheets are laid as roofing, each strip will have at its edge a plain margin of uniform thickness and of a single color.

Many modifications may be made in the physical embodiment of the invention without departing from its spirit.
